Gov. Nixon 'hardened' by Saturday protests

After another violent night of protests in Ferguson, Missouri, Gov. Jay Nixon said on Sunday that he was "hardened."

"Across the nation there are deep wounds, and when you scratch them again, they hurt," the Democratic governor said Sunday on CNN's "State of the Union." "It's important that we get this right; this is a big matter."

All eyes have been focused on the small suburb of Ferguson outside St. Louis after 18-year-old Michael Brown was shot and killed by a police officer, later identified as Darren Wilson. Over the weekend, after protests continued, Nixon called for a state of emergency that included a midnight to 5 a.m. curfew. On Saturday night, many ignored Nixon's orders, and one protester was reportedly shot by another.

"There's a tremendous amount of angst about the facts in this case," Nixon said. "Thousands of people spoke last night, thousands of people marched and not a single gunshot was fired by police last night."

"We are trying to use the least amount of force to provide people the ability to speak," he said.

In regard to when the community can expect the curfew to end, Nixon said that "will be judged by the community."
